Description
Technical field
The present invention relates to building composite foundation, especially a kind of pipe pile composite foundations.
Background technology
At present generally there is foundation treatment mode in specification：CFG pile composite foundations, cement mixing pile composite foundation, rigid pile
Composite foundation.These foundation treatment modes all have the shortcomings that one it is common：Time-consuming too long, cost of labor accounting is too big, is difficult to
Ensure pile quality.Present cost of labor proportion in entire project cost alreadys exceed 30%, but also on continuing
Rise.
Wherein, CFG, every stake machine can only make a call to 6 ~ 8 daily for cement mixing pile etc., and CFG, cement mixing pile beats
Foundation trench could be excavated after at least waiting 28 days after complete stake, time-consuming, greatly improves building cost.
Invention content
The purpose of the present invention is to provide a kind of short construction period, reliable in quality, it is easy for construction, increase economic efficiency, have
Effect ground improves the pipe pile composite foundation of foundation bearing capacity, with overcome common composite foundation take too long, cost of labor accounting it is too big,
The shortcomings of being difficult to ensure pile quality.
The object of the present invention is achieved like this：
A kind of pipe pile composite foundation, including lower layer and upper layer, it is characterised in that：The lower layer is prefabricated tubular pile layer, and upper layer is cotton-padded mattress
Bed course is spaced from each other between adjacent prefabricated tubular pile in prefabricated tubular pile layer；The prefabricated tubular pile top closure, the mattress layer by
Sandstone mixes, and on ground and prefabricated tubular pile top surface, mattress layer area coverage is more than where prefabricated tubular pile mattress layer place mat
Range.When design, stake top absolute altitude is lower 300 ~ 400mm than sole plate bottom absolute altitude（Because mattress layer thickness is 200 ~ 300mm, element
Concrete mats layer thickness is 100mm）.
The purpose of the present invention can also use following technical measures to solve：
As more specific scheme, distance is 3.5 to 4.5 times of prefabricated tubular pile diameter between the contiguous prefabricated pile pile.It is same
Building concentration ground can squeeze into more prefabricated tubular piles, use and be welded to connect between two prefabricated tubular piles up and down of same position.
Specific stake is long, stake diameter, stake spacing can carry out appropriately configured according to the result of calculation of disparity items, and stake top absolute altitude is the sole plate bottom of than
Absolute altitude low 300 to 400mm.
As further embodiment, the prefabricated tubular pile top is equipped with sealing plate, and sealing plate closes prefabricated tubular pile top nozzle.
The top of prefabricated tubular pile carries steel ring, and sealing plate uses the steel plate equal with prefabricated tubular pile diameter, the steel ring of steel plate and prefabricated tubular pile
Firm welding.
Alternatively, the prefabricated tubular pile top is by filling sandwich layer closing.When stake top needs to cut stake, this side is taken
Formula is by prefabricated tubular pile top closure.
The prefabricated tubular pile inner cavity, which corresponds to, fills sandwich layer equipped with sealing plate, and sealing plate seals the position of certain altitude in prefabricated tubular pile
It closes.
The filling sandwich layer is C30 microdilatancy pea gravel concreten layers, thickness 500mm.
As further embodiment, the thickness of the mattress layer is 200mm to 300mm.
The mattress layer is coarse sand, middle sand, macadam gradating sandstone, and the grain size of rubble is less than or equal to 30mm, and mattress layer rams
Degree of filling out（The ratio of mattress layer thickness and virtual resurfacing thickness after compacting）Less than or equal to 0.9.Rubble cannot use cobble.
Plain concrete cushion layer and sole plate are equipped on the mattress layer successively, plain concrete cushion layer is located at mattress layer area
Within the scope of.
The mattress layer periphery has more 400mm or more than plain concrete cushion layer.
Beneficial effects of the present invention are as follows：
（1）Such pipe pile composite foundation uses prefabricated tubular pile instead of CFG or cement mixing pile, also, to prefabricated tubular pile
Top is closed, and it is guaranteed to save duration, pile quality, meanwhile, and more more economical than common pipe pile foundation, more convenient apply
It is work, more more economical than common pipe pile foundation, it can speed up the work, save a large amount of durations, to generate substantial economics；
（2）Prefabricated tubular pile pile quality used by such pipe pile composite foundation is secure, because pile pile is finished peg, in factory
It is directly prefabricated；
（3）Prefabricated tubular pile used by such pipe pile composite foundation is more more economical than common pipe pile foundation, because comparing commonly
Pile foundation, which eliminates, to be anchored into cushion cap or sole plate reinforcing bar, eliminates core grouted concrete；
（4）Such pipe pile composite foundation can once excavate in place, not need brick mold, facilitate construction；
（5）Such pipe pile composite foundation is suitable for the basement process of various types of multilayers or skyscraper（As long as being suitble to stake
The soil property of base construction is all right）.
Description of the drawings
Fig. 1 is one embodiment of the invention schematic cross-sectional view.
Fig. 2 is that Fig. 1 middle pipe stake tops portion connects enlarged structure schematic diagram.
Fig. 3 is to connect enlarged structure schematic diagram in the present invention at the top of another embodiment pile pile.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and embodiments.
Embodiment one, a kind of shown referring to Fig. 1 and Fig. 2, pipe pile composite foundation, including lower layer and upper layer, the lower layer are
Prefabricated tubular pile layer, upper layer are mattress layer 4, are spaced from each other between the inner adjacent prefabricated tubular pile 1 of prefabricated tubular pile layer 3；The prefabricated pipe
